ROLLER SKATE.

Application medJanuary 14, 1922. Serial No. 529,232.

To all' whom it may concern:

Be it known that I, Tnnononn FEDUN,

citizen of Poland, residing at Detroit, in

the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Roller Skates, of which the following is a specification.

This invention relates to new and useful improvements in roller skates, the primary object of the invention being to provide a skate of the two roller type, a front and rear roller, and a simple, inexpensive means for producing a strong and durable skate.

Another important object of the invention is vto provide a new and simple mounting for the rollers which embody shock absorber means.

Another object of the invention resides in the provision of an eiiicient ball bearing roller and means for mounting the same whereby it can be easily removed from the s kate to exchange its position with the other roller of the skate or to facilitate repairs.

A still further object of 'the invention is yto provide simple and eiicient means for eii'ecting adjustment of the skate plate for the adaption thereof to dierent size shoes.

Other objects and advantages of 'the invention will becomeapparent during the course of the following description.

In the accompanying drawings forming a part of the description and wherein like numerals are employed to designate like parts throughout the several views;

Figure 1 is a side elevation of the skate.

Figure 2 is a top plan of the same.

Figure 3 is a transverse section thereof on the line 3 3 of Figure 1.

Figure 4 is a transverse section of the skate taken on the line 4 4 of Figure 1.

Figure 5 is a fragmentary, longitudinal section through the skate on -the line 5-5 of Figure 2.

Figure 6 is a transverse section taken through Figure 5.

Figure 7 is a section of the roller taken on the line 7-7 of Figure 3.

Figure 8 is a plan of the fork plate prior to its being bent.

Figure 9 is a plan of an attaching plate prior to its being bent and which forms a art of the shock absorber means.

Figure 12 is a fragmentary plan of "one of the skate plate sections.

Referrlng now more particularly to the drawings wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numeral 1 designates a skate plate in its entirety and which embodies a pair of relatively adjustable sections, each of which is equipped with a reduced extension 2, havin an elongated slot 3 therein. rlhese extenslons 2 are adapted to be arranged in overlapping relationship so that their slots align. These extensions are retained in overlapping relationship by means of a guide 4 assuming the form of a rectangular (in cross section) sleeve which is formed from a single blank of material as disclosed in Figure 10. This blank is provided with a central square opening 5, while a pair of the oppositely disposed edges of the blank are provided each with a semi-circular cut out portion 6, which portions are arranged directly opposite each other and the opening 5. This blank is folded upon a pair of lines 7 parallel to the edges of the blank having the cut out portions 6 therein whereby a sleeve is provided which has its top provided with the square opening 5, and the notched ed es of the blank are arranged contiguous so t at the two cut out portions 6 form a circular openin in the bottom of the sleeve. A bolt 8 is a apted to be passed through the openings in the sleeve and also through the a igning slots in the skate plate extensions it being observed in Figure 5 that the bolt is equipped with a square portion 9 to lit the square opening 5 in the sleeve to prevent turning movement of the bolt. A nut 10 is adapted to be threaded upon the bolt to abut the bottom of the sleeve for retaining the skate plate sections in adjusted positions.

Each skate plate section is equipped with clamp means, the toe section having the ordinary type of screw adjustment clamp 11 associated therewith, while the heel section of the skate plate is provided with upstanding apertured extensions 12 for association with a foot strap.

As the means for mounting the front and rear rollers on the skate are of the same construction, a description of one will suiiice for both. As best understood from. Figures 9 and' 1, en attaching plate 13 is provided with a plurality of apertures 14 so that it may be riveted to the under side of the skate plate. This attaching plate is provided with forwardly and rearwardly extending wings or extensions 15, each of which is equipped with a central opening 16 for a purpose which will presently be described. These wings are adapted to be bent at right angles to the body portion of the attaching plate and to depend from the bottom of the skate plate.

The fork plate 17 which is more clearly shown in Figure 8, consists of a body portion .having a pair of its oppositely disposed edges provided with laterally extending wings or extensions 18, each of which is provided with a central opening 19, it being observed 'that these wings are of the same construction as the wings 15 oi the attaching plate. rlhe wings of the fork plate are likewise adapted to be bent at right an les to the body portion of the plate and to is arranged inside of and in contact with the wings of the attaching plate, so that the aperture ot-all wings align for the passage of a bolt 20. As best seen in Figure 3, a rectangular block of rubber or other pliable material 21 is adapted to be disposed between the attaching and fork plates to form a shock absorber, and is equipped with an opening therethrough for the passage ot the bolt 20. It will of course be understood that the top edges of the wings 18 of t-he fork plate are spaced from the' attaching plate so as to permit relative movement of the two plates when the block of rubber is called upon to function.

The fork plate 17 is also provided on opposite edges with elongated extensions 22, which when bent in thev opposite direction from the wings 18 are adapted to be disposed at right angles to the wings 18 to provide a fork for mounting the skate roller. These extensions 22 depend from the bottom of the skate plate and the lower end ot each is provided with an aperture 23, one of which is equipped with a small neck for lthe receptionot a key carried by the shank ot' a bolt 24 which passes through the apertures 23 to orrn an axle for a rollerL The roller consists of a Jframe made up of a pair of disks 25, each of which has its outer edge equipped with a laterally extending annular f ange 26. Each disk is also equipped with a central, enlarged opening which is surrounded by a laterally extending annular liange 28. These two disks provide a frame for a rubber roller or disk 27 havying its tread pertion 28 enlarged laterally to each side, so that when the disk 27 is clamped between the two frame disks 25,

y the 'tread 28 will be supported upon the antlenves 28 of the two traine disks. rEhe .L 1 .a .uw 3 Lcher elsa and two trarne disks 'bearing races 31 spaced apart.

It will also be noted that the central opening of the roller disk which receives a portion of the axle bolt 24 is considerably smaller in diameter than the central opening ofthe disks 25 so as to provide means for retaining cupped ball Each ball ing 32, which is adapted to be clamped .in lixed relation to the axle 24. Ball bearings 33 are retained in Contact with the bearings 32 by means of cups 34 which are adapted to be snugly received in the iianged central openings of the frame disks with their inner ends abutting opposite sides of the roller disk 27. The relative outer ends of the cups 34 are curved inwardly toward the centers thereof to prevent displacement of the ball bearings.

The foregoing description and the accompanying drawings have reference to the preferred or approved embodiments of my invention. It is to be understood however, that such changes may be made in construction and arrangement of parts, materials, dimensions, etc., as may prove expedient and fall within the scope of the appended claims.

Having thus described and illustrated my invention, what I now claim as new and desire to secure by Letters Patent is:
